The following features have been added to or improved for PC-BSD® 9.1:

Based on FreeBSD 9.1, which includes improved Intel video support. The Release Notes for FreeBSD 9.1 list the new features and drivers introduced in FreeBSD 9.1. URL DOES NOT EXIST YET

The PC-BSD® installer has been revamped to separate pre-installation tasks from post-installation tasks. This makes it easier to automate the roll-out of multiple installations because the end-user can configure their account information and display settings before logging in for the first time.

The PC-BSD® installer now sets its default settings according to the hardware installed. 64-bit systems containing over 2GB of RAM will default to the ZFS filesystem whereas 32-bit systems and any system containing less than 2GB of RAM will default to UFS+SUJ. Systems containing more than 2GB of RAM will default to the KDE desktop and all other systems will default to the LXDE desktop. A hardware compatibility icon within the installer allows the user to see at a glance if their video card, Ethernet card, wireless card, and sound card are compatible with PC-BSD®.

The ability to perform a network install has been removed from the graphical installer. The scriptable back-end still provides the variables needed for network installations.

The ZFS section of the PC-BSD® installer now allows you to set ZFS properties such as compression and quotas, create datasets, and import existing ZFS pools.

Multiple Boot Environments support allows systems formatted with ZFS to create alternate bootable snapshots. These can be used for testing purposes or to create a bootable backup of the boot environment before performing an upgrade.

Warden® is now built into the operating system and available through Control Panel. It can now be used to manage multiple jails.

Warden® now supports the creation of three types of jails: traditional FreeBSD jails for running network services, (a less secure) ports jail for safely installing and running FreeBSD ports/packages from your PC-BSD® system, and the installation of Linux within a jail.

Warden® now supports the management of ZFS snapshots on a per-jail basis.

Update Manager has been integrated into Warden®. Combined with the meta-package support, it is now easier than ever to install software into a jail and to keep that software up-to-date.

AppCafe® now shows the number of available PBIs and supports automatic updating.

EasyPBI is now available through Control Panel, making it easier than ever to convert existing FreeBSD ports to PC-BSD® PBIs.

An About icon has been added to the Control Panel, making it easy to determine the PC-BSD® version, which desktops, and the version of X that have been installed.

An Active Directory & LDAP GUI has been added to Control Panel, allowing you to set the client information for connecting to Active Directory servers.

A Hardware Compatibility icon has been added to the control panel, providing a quick overview of detected hardware devices.

The GDM Configuration GUI has been added to Control Panel and can be used to configure auto-login and remote login through XDMCP.

A Mount Tray icon has been added to the Control Panel and System Tray, allowing easy access to USB drives.

A Sound Configuration icon has been added to the Control Panel and can be used to test sound or change the default audio device.
